LOBULARIA CORIACEA. (A. coriaceum, Esper.) " Semipedalis, nee

SUBFAMILY III. SPOGGODIN^E. 



Alcyonidce membranacece, et interne spatiosc celluloses; polypis non re- 

 tractilibus. 



Membranaceous and internally spatiously cellular; polyps not re- 

 tractile. 



GENUS SPOGGODIA. LESSON. 



Alcyonidce ramosce, interne spatiose celluksce ; polypis minutis, non retrac- 

 tilibus, coacervatis, acervis spiculo-armatis. 



Ramose Alcyonidse, internally very open cellular; polyps minute, not 

 retractile, in clusters which are armed with calcareous spicula. 



The texture of the stems and branches is very peculiar in the 

 large open cells, separated by thin, semimembranous partitions. The 

 exterior is stiffened by numerous long, calcareous spicula, which are 

 exsertile about the little clusters of polyps, that are scattered over the
